Coherent control of one-photon and two-photon optical fluorescence channels in three-level ladder system Conference Paper

We consider a three-level atomic system interacting with two coherent fields in the ladder configuration. Namely, the pumping field couples the ground and first excited state while the driving field interacts with the two excited states. The intensity spectrum of resonant optical fluorescence at the two-photon transition is studied. It is shown that coherent driving in this scheme allows for efficient control of fluorescence distribution between the one-photon (elastic with respect to pumping field) and two-photon (anti-Stoke Raman with respect to the driving field) channels.
